ENVELOP-MACHIN E.

SPECIFICATION forming part of Letters Patent No. 721,701, dated March 3,1903. Application filed October 16, 1902. Seri 110127520. (No model-3 Toail whom it may concern:

Be it known that I, GEORGE H. HAsLOP, a citizen oftheUnitedStates,residing atWorcester, in the county of Worcester andState of Massachusetts, have invented a new'and useful Envelop-Machine;of which the following is a specification.

The object of this invention is to improve that class ofenvelop-machines in which the folding-bed moves up and down verticallyand in which the envelop is pushed 0d of the folding-bed when it is inits lowest position. An example of this style of machine is shown inpatent to Smythe, No. 191,575, granted June 22, 1869. this character torun at a high speed it has been found necessary to provide a veryaccurate guiding means for the vertically-moving folding-bed and meanswhereby the envelop can be accurately and positively ejected off of thefolding-bed. To accomplish these ends, I provide a guide-support for thefolding-bed which has a dovetailed groove cut therein. The folding-bedis provided with a dovetailed tenon engaging said groove, and a taperedgib is interposed between the tenon and the guide, so that the parts canbe very accuratelyadjusted and all wear taken up. A stopping-piece issecured to the bottom of the tenon to accurately define and determinethe upper position of the bed when it receives the envelop. It has beencustomary heretofore in devices of this kind either to have thepusher-fingers move across the face of the bed or across the bed inslots out therein. The first of these devices has been found to beobjectionable, because the slightest derangement of the parts or anyinaccuracy the ends of the pusher-arms V-shaped, so

will cause the pusher-fingers to ride over the envelop or the envelopsto stick between the pushers and the top surface of the bed, cloggingthe machine and tearing the envelops. The other of "these devices hasbeen found objectionable, as the slots in the bed are apt to mar orbruise the envelop. To overcome this objection, I provide a mechanismwhich as the folding-bed drops down will slightly separate the rear edgeof the envelop from the surface of the bed, and I preferably make Indeveloping a machine of tween its two sides.

that they will engage the relatively elevated rear edge of the envelopand push the en velop accurately off of the folding-bed. This overcomesthe objection previously noted and still leaves the surface of thefolding-bed smooth, so as not to mar the envelop.

The invention further consists of certain details of constructionhereinafter pointed out, and defined in the claims.

pared with the raised position shown in Fig. 1.

Fig. 3 is a plan View of the support and folding-bed. Fig. 4 isafrontview of these parts. Fig. 5 is a rear view of these parts; and Fig. 6 isa perspective view, on an enlarged scale, illustrating a detail.

Referring to the drawings and in detail, A designates the table.

B designates the guide-support, having a flange B, which is bolted tothe under side of the table. A dovetail groove Ois cut in theguide-support.

D designates the folding-bed, made in the form of an inverted L andhaving ribs D be- A dovetail tenon E projects from the folding-bed D.The foldingbed is arranged in an aperture cut in the table, as shown.The folding -bed is surrounded by the usual four folders, two of which,F F, are shown. These folders are arranged slightly below the level ofthe-table A. One side of the dovetail tenon is out on an incline 10, asshown. A tapered gib 11 is arranged between this inclinedside and'thecorresponding side of the dovetail groove 0. This gib is provided with aslotted shoulder 12, engaging which is the head of a screw 13 and collar14, secured thereon. The screw is tapped intothe tenon E, and byadjusting the screw the tenon can be very accurately fitted to thegroove, so that the bed will have an accurate movement and so that theparts can be adjusted for wear. A stop-- piece is secured to the bottomof the tenon by screws 16 and is arranged to strike on the bottom of theguide-support B to define the upper position of the bed. Separated pins18 18 are fitted in small holes cut in the bed D and in small bracketsor projections extending from the upright side of the foldingbed. Eachof these separated pins has a spring 19 thereon engaging a pin 20inserted in the separated pins. A connecting-piece 21 connects the endsof the separated pins 18. An arm 22, secured to a support 23, engagesthis connecting-piece. When the bed is in its lifted position, as shownin Fig. 1, the ends of these pins will be below the top surface of thefolding-bed; but when the folding-bed is reciprocated down to its lowestposition, as shown in Fig. 2, the ends of the separated pins willproject slightly up above the surface of the folding-bed and willseparate the rear edge of the envelop from the surface of thefolding-bed.

The folding-bed is reciprocated by the following means: A slot 24 is cutin the guidesupport B. A stud 25 is secured in the upright side of thefolding-bed. A link 26 engages this stud and a pivoted arm 27, whichcarries a roll 28, engaging a cam 29, arranged on the operating-shaft ofthe machine. A spring 30 is arranged to hold the roll 28 in engagementwith the cam.

31 designates the pusher-arms. The ends of these pusher-arms areV-shaped or notched, as at 32, for the purpose mentioned. Thesepusher-arms work in slots cut in the table and are arranged in positionoutside of the lifting-pins to move across the top surface of thefolding-bed when the same is in lowered position.

The rear folder is slotted in the usual manner to allow the pusher-armsto pass forward under the same. The pusher-arms are connected by a piece33, which connects by link 34 to a pivoted lever 35, which connects bylink 36 to a pivoted arm 37, having a roll 38, engaging a cam 39,secured on the operatingshaft of the machine. A spring is used to keepthe roll 38 on its cam.

The parts are timed to operate as before described, and by the improvedconstructions herein particularly pointed out a very accurately runningdevice which can be readily adjusted for wear is provided, and theenvelop is accurately delivered from the surface of the lowered bedwithout any possibility of being caught under the pusher-arms,

and a smooth face for the folding-bed is still employed.

The details and arrangements herein described may be modified by askilled mechanic without departing from the scope of my invention asexpressed in the claims.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-- 1. In an envelop-machine, the combinationof a vertically-moving folding-bed, means for separating an edge of theenvelop from the surface of the bed, and pushers arranged to move acrosssaid bed to engage said edge of the envelop and push the envelop off ofthe bed.

2. In an envelop-machine, the combination of a vertically-movingfolding-bed, means for separating an edge of the envelop from thesurface of the bed, and notched pushers arranged to move across said bedto engage said edge of the envelop and push the envelop oif of the bed.

3. The combination in an envelop-machine, of a vertically-movingfolding-bed, separating-pins carried thereby and housed within said bed,and a stop for engaging said separating-pins arranged so that as a beddrops, the lifting-pins will separate an edge of the envelop from thesurface of the folding-bed.

4. The combination in an envelop-machine, of a vertically-movingfolding-bed, separating-pins housed therein, springs holding the pins intheir lowest position, a piece connecting said pins, and a fixed stopfor engaging said connecting-piece.

5. The combination in an envelop-machine of the table, a guide-supportbolted to the under side of the same and having a dovetailed groove, aslot cut in said guide-support, a folding-bed having a dovetailed tenonengaging said groove, one side of said tenon being cut on an incline, atapered gib arranged between said inclined side and one side of thedovetailed groove in the support, means for adj nsting said gib, a studsecured to said folding-bed and projecting through the slot in saidguide-support, and operating connections for said folding-bed engagingsaid stud.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

GEO. II. IIASLOP.
